' To all whom it may concern: I

Be vit known that we, FRANK J. Marc'nn'r'rn and RICHARD RADIIJATZ, citizens of the United States, 're- I siding at ilwaukee, in the county of, Milwaukee and 'State of \Visconsin, have invented certain new and ,useful Improvements in Vacuum Cleaning Apparatus, v of which the following is a specification, reference being bad to the accompanying drawing, forming a part thereof. I

1 This invention relates to apparatus for removing dust and dirt from various articles such ,as carpets, furniture, floors, walls or the like; Its main objects areto simplify and improve the constructionand operation of the vacuum-producing and controlling means to reduce the cost of apparatus of this class; to economize space andpower in its installation and operation to save time, labor, careandfattention in the operation of the system and in keeping it in workingbrder; to sterilize or render innocuous the air and any dust which may be discharged therewithirom the system into the outside air; and generally to simplify and. improve the construction and operation of apparatusof this class. The invention consists' in certain novel'featuresof construction -and- ,in the peculiar arrangement and combinations of parts hereinafter particularly described and pointed out'in the claims-l In the accompanying which'illustratesgonly I one of the various forms or'eihliodiments of the inven- -tion 1ike characters designate the same parts in the severalfigurea' I p Figure 1 is a general view partly'in elevation and partly. in vertical section of apparatus embodying the invention;- Fig. 2. is a view on anenla'rged scale partly in elevation and partly in vertical section of a part of the apparatus shown in Fig. '1; Fig.1 3 is enlarged horizontal section on. thefline .3 3, Fig.1; Fig.4 is a longitudinal section on an enlarged scale of one of the c ontrolling valves which are associated with the cleantools, implements or apparatus to be operated by thevacuum are connected. .1 or example-as shown in Fig. 1, a sweeper, nozzle or suction head 6 is det achably said pixie, which is provided "-"at convenient-points .with stubs'orfbranchesf each having a valve' d. The various tools or implements used witlithe system, the branches of the suction main and the hose sections, are provided with couplings e 0 and f for readily connecting andj discoimecting them,

tithe several sweepers. and other portable cleaning Mplinents, provided in or} near theirhandles, as l wn far id 5'with valve b for more'readil y them all from thesuc tion main and thus preing tools, and Fig.5 is a crow section of the on .the

venting waste of power whenever or one tool is changed for another. The pipe :1 leads into the dust separator g, in which it is provided with a tangential nozzle I; or is bent as shown in Fig. 3, so as to give a vertical movement the air and thereby facilitate the separation of the dust lower part of the separator it; is discontinued and dirt, therefrom. The is preferably conical orupper part of a pr mary funnel shaped, termihating at the bottom in an opening access to the interior of the separator, and if desired, for removing from time totime the dust anddirt which collect therein.

For removing-the dust and dirt without openingthe: v

I I which is provided with a door or closure '11 for affording and on the opposite side a valve m. Another water supp y with a valve 0 is connected with the top of the separator and terminates therein with a rose or sprinkler head p, for loosening and washing down into the discharge pipe l the dirt and dust which are apt to cake and stick to the, walls of the separator. 1 v Fromthe separator g a. p'pe q, having a check valve 1- which closes towards the separaton le ads to an aspirator or ejector a. This checkvalve may however, be otherwise located, provided his arranged to prevent back flow of air into not in operation.

As shown Fig; 1, the pipe q preferably opens up ward into the central and upper part of the separator wherethe'air is the least agitated afidyisfreest from dust The blast or j et nozzle of the aspirator is connected by a pipe 1 with a steam boiler brother source of fluid pressure (not shown,) and this pipe is preferably provided with a valve 'u-for manually shutting off the .fluid pressure supply fromthe apparatus,

preferably made holreceive along spiral in Fig. 2, so as to admit steam or other to the aspirator. The piston chamber is connected Jat the and opposite the valve by a pipe 2 with the primary pipe n provided the suction main when the aspirator is sspirator is controlled by an automatic governor t'fthe" operation oi which is mainly controlled by the valves spring 2, which normally holds the valve open as shown' pressure medium dust separator g, or with any other convenient part of" maintained. A

, The supply of steam or other pressure medium to the in 2, a form of governor suitable for the purpose" valve w, serves to adjust the tension of the spring 2 so tion of the apparatus or as the result of leakage; the

that the valve will be closed by any desired degree of vacuum; v

A waste pipe 4, leading ironi the lower endsofvthe piston and valve chambera carries off any water of condensation that ,may form therein and would otherwise interfei e with the proper operation of the governor.

The use of a long spring 2 which is permitted by allowing it to extend through the piston head and valve without increasing theleng/th of the governor, avoids any considerable variationin the tension of the spring within the limits of the movementof the valve andpiston. p L

A secondary dust separator 5. for-removing any fine dust that may be drawn with the air irom the primary separator g and for separating water of condensation and V dirt horn-the steamand air-is preferably provided, and connected with the discharge of the aspir'ator s by a tube or pipe 6, which serves as a sterilizing and mixing chamber, as hereinafter explained. p

- theupper part of the separator 5 anfair and steam outlet pipe leads into a chimney, stack or flue, or the air which has been'sterilized and freedfrom' dust I and dirt may be discharged dir'ectlyinto the atmosphere. I g p A discharge pipe 8, preferably forined. or provided with a trap, lea'dsfrom the lower part oi the separator 5 intoa seweror other convenient waste-conduit.

The system operatesasjollows'. The valve 1;; being opened and steam or other fluid under pressure being admitted through the pipe t to-the sspirator s, a vacuum '0! low pressure is produced in the apparatus andair with dust and dirt taken'up or collected by one-or more cleaning tools or implements b, is drawn through the vsne't'itu'rpipe a into the separator g by the action of thesteam or other pressure fiuid in said aspirator From the separator =g the-air, from which the coarse dirt and thegreater part of the-fine dust have been separated, is

the pipeq and check valve rjnto the aspirator, from which it is discharged with thet stealnor other fluid employed to operate the'iispiraton- I of a rise in the vacuum tothe liniit at which'the': ernor v is adjusted to cut off the supply'of stea 'ni or,

other fluidundier'pressure'tg theaspirator, by reason of 1 a complete or partial stoppage of the admission of air into the pipe-a, asfor example, whfijl work withit cl ea'n ing implement is discontinued or its connection ,with said pipe is off,-or when an implement using inore ai;' is exchanged-for one using less, the increased 'vacuwhich results, acting on the valve 10 and piston lieodz valve,' cuts oft the supply of steam or pressure fluid to thehspirator and thereby effects tiuues inoperation willbedeposited in or drawn towards sepmtonlwhich thuo "we; as a low pres sure reservoir as wellas a' dust separator and dint re-f Whenever an the result 01 the norrnal opera- 1 The opera. {moi pressure falls to the liinit at wli ich the governor is adto admit steam or other pressuremedium to the aspirator, the spring 3 opens the valve w; The aspira- .tor is thus started and continues to operate until the pressure rises to the limit at which the governor is adjusted to close said valve. The aspirator will thus' be automatically stopped and started'at varyingintervalsv while one'or m0re cleaning implements are in use, and will continue in operation, consuming steam orfiu id under pressure, for longer or shorter periods according to the varying demands upon the system. For example, in a plant having an aspirator designed by continuous operation to keep a. certain number of sweepers at work simultaneously; if halithat number are cut out by closing the controlling-valves b, the aspixator will be in service approximately only half the time.

In like. mannerin a fivesweeper plant the aspirstofwill have.

to operate but one-fifth oi the time to maintain the required vacuum for the continuous operation of a single sweeper. Itwill'be seen, therefore, that theaction'of the governor which controls the consumption'of power for-the operation of the vacuums-producing means isitself controlled by the valves 1) which are associated with the cleaning implementsoand are constantly at hand. V 7' The limits at which the governor acts to stop and start the aspirator-al varied for maintaining a higher 01- lower pressure by the adjustment of the screw 3 which controlsethel ten'sion of the spring z. V

The dust dirt collected in the lower part of the separator g riiay be removed from-time to time by open:- i

ing the. dooryiioi preferably without-opening the doorby opening the-valve m and either or both of thevalves k and o. In thelatter case the wateradmittedinto the separator thronglfi either ,or both of the: pipes and n loosens-and washes the and dust into the discharge pipe I, which conducts them off into a: sewer or onir' convenient conduit or recepta.cle.,
